Version 0.9.8.7 in Beta release

Just in case it has any major problems have limited the release to the 100 or so beta testers at present.

Main changes are:

1. Fix in TCP capture file, that gave zero figures.
2. Extra error trapping in the registration window
3. New Calibrate tbbMeter option under the Test Tools menu - on upgrading the test will auto run (via popup) after 60 seconds. Calibration will measure how many bytes a known 5 MB file counts as when downloaded. This should allow the meter to cope with situations where AV/firewall software interes with data - e.g. Kaspersky AV
4. You can disable this calibration/correction in the test tools menu
5. About window shows the current correction factor.

Re: Now released to everyone

OK on my Windows 7 PCs running Vista and Norton; but a disaster on the old XP machine which runs Kapersky where despite manually setting both the install files and program to "allow" (which I had to do) as Kapersky deemed them "dangerous" it is still blocking elements so the graph is unintelligible and shows a continuous yellow block or nothing at all and the kbps legend has translated into an elaborate italic. Uninstall/reinstall leaves the same situation (even now with the earlier version available on the download page). The icon though appears to be operating correctly. Kapersky: I hate 'em. Data calibration shows as "infinity", so presumably doesn't work with Kapersky?

EDITS: Bit more info: reset calibration and the graph shows correctly, but with blank upload/download. Recalibrate (which runs for 10 mins) and it goes funny again. And finally after a further couple of attempts now calibration shows speed axis as "Gbps" with an intermittent display on the graph, now I know I'm on VDSL2 but it's not that fast!
